Hema Explorer - Can I use my existing maps with the app?
You may have a collection of maps acquired during use of some earlier GPS device.
These maps may be in various formats etc. (such as ECW, OZF, QCT, etc.).
If you have for example, OziExplorer format maps, you could use them by buying and downloading the OziExplorer app for Android (see http://www.oziexplorer.com)
The Hema Explorer app cannot utilise these maps. The app does not allow loading of external map sources, and the maps are not in the correct format for use by the app.
